Drilling a wall hole and installing wall embedded pipe

• For metal frame or metal board walls, be sure to use a wall embedded pipe
and wall hole cover in the feed-through hole to prevent possible heat, electrical
shock, or fi re.
• Be sure to caulk the gaps around the pipes with caulking material to prevent
water leakage.
1) Drill a feed-through hole with a φ2-9/16 inch (65mm) (for 09/12 class),
φ3-1/8 inch (80mm) (for 18/24 class) diameter through the wall at a
downward angle toward the outside.
2) Insert a wall embedded pipe into the hole.
3) Insert a wall hole cover into wall pipe.
4) After completing refrigerant piping, wiring, and drain piping, caulk the pipe
hole gap with putty.

1) Attach the drain hose to the underside of the refrigerant pipes with
adhesive v inyl tape.
2) Wrap the refrigerant pipes and drain hose together with
tape.
3) Pass the drain hose and refrigerant pipes through the wall hole, then set
the indoor unit on the
at the top of the indoor unit as a guide.
4) Open the front panel (Refer to "Installation Tips"on page 10), then open
the service lid (Refer to "Indoor Unit Installation Drawings"on page 4).
5) Pass the inter-unit wire from the outdoor unit through the feed-through
wall hole and pass to the front of indoor unit from the back. Then pull
them at front side. Bend the ends of cable tie wires upward for easier
work in advance.
6) Press the bottom frame of the indoor unit with both hands to set it on the
mounting plate hooks. Make sure the wire leads do not catch on the
A
edge of the indoor unit.
